If you believe that, you better turn yourself into the police right now since you are guilty.
And sure, an abomination is guilty. And abominations are less than 1% of mages. So the 99% should be killed on what, a possibility of them becoming one? We argued this before, if that is the case then all people should be arrested and/or killed because they may kill someone. Oh wait, you said that was stupid, countering your own beliefs.
Why i should do that even if im breaking law such action would be simple stupid... oh we are talking about what is innocent by law or just about human nature? Well i can quickly change law that says mages are guilty now they are guilty according to law see im very flexible. 
1 %? yeah we saw for example circle in ferelden ups bad example then maybe circle in kirkwall ups bad example abomnation galore not rly 1 % and made list damage caused by mages...
